Abstract

  • Background: No consensus on the preferred means of evaluating patients after surgical placement of an inflatable penile prosthesis (IPP) currently exists. Many self-assessment questionnaires are available, but none specifically targets patients with IPPs. The purpose of this study was to assess the construct validity of the Patient Global Impression of Improvement (PGI-I) for evaluating patient satisfaction after placement of an IPP.; Methods: We conducted a multicenter prospective trial and enrolled patients who elected to have a 3-piece IPP surgically implanted. Postoperatively, patients completed the Sexual Health Inventory for Men (SHIM), Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), and PGI-I at 3, 6, and 12 months. The Pearson correlation coefficient (PCC) was used to compare scores over time.; Results: Fifty-six patients were enrolled, and complete data were available for 39 patients. At 3 months, the PGI-I correlated with the EDITS (PCC = 0.83, P<0.01) and with the SHIM (PCC = 0.73, P<0.01). At 6 months, the PGI-I correlated with the EDITS (PCC = 0.74, P<0.01). At 6 months, the PCC between the PGI-I and the SHIM was 0.41 (P<0.05). At 12 months, the PCC between the PGI-I and the EDITS was 0.83 (P<0.01), and the PCC between the PGI-I and the SHIM was 0.61 (P<0.01).; Conclusions: Overall, the PGI-I appears to correlate with both the SHIM and EDITS and is a valid evaluation tool for use with patients after IPP placement.
